Abnormal atrial strain with speckle-tracking echocardiography predicts the arrhythmic substrate of atypical right atrial flutter
2214-0271/© 2017 Heart Rhythm Society. Published by Elsevier Inc. This is an op under the CC BY-NC-ND license (http://creativecommons.org/licenses/by-nc-nd/4 Introduction Atypical atrial flutter is defined as macroreentrant atrial tachycardia (AT) that does not involve the cavotricuspid isthmus; a variety of reentrant circuits may include reentry around the mitral valve annulus or scar tissue w...
متن کاملMethodological Gaps in Left Atrial Function Assessment by 2D Speckle Tracking Echocardiography
The assessment of left atrial (LA) function is used in various cardiovascular diseases. LA plays a complementary role in cardiac performance by modulating left ventricular (LV) function. Transthoracic two-dimensional (2D) phasic volumes and Doppler echocardiography can measure LA function non‑invasively. However, evaluation of LA deformation derived from 2D speckle tracking echocardiography (ST...
متن کاملEvaluation of right atrial function using right atrial speckle tracking analysis in patients with pulmonary artery hypertension
BACKGROUND In patients with pulmonary artery hypertension (PAH), right ventricular pressure overload eventually causes right heart failure (RHF), leading to a poor prognosis. Right atrial (RA) overload and RA dysfunction occur in patients with PAH-complicated RHF. OBJECTIVES We evaluated RA function using right atrial longitudinal strain (RALS) by two-dimensional speckle tracking echocardiogr...
متن کاملLeft atrial function examination of healthy individuals with 2D speckle-tracking imaging
The aim of the present study was to determine the left atrial (LA) function of healthy individuals of various ages by examining their LA strain and time-to-peak (TP) using 2D speckle-tracking imaging (2DSTI). In addition, the study investigated the potential value of STI in clinical applications. The 142 volunteers were divided into three age groups, namely, young adult, middle-aged and elderly...
